PIPE-JOINT.

Specification of Letters Patent.

Application led March 26, 1913. Serial No. 756,947.

To all H'm'm it 11mg/ concern Be it known that I. PINK Vai'uux, acitizen of the I Inited States. residing at Eustace. iu the county ot'Henderson and State of Texas. have invented new and useful Improvementsin Pipe-Joints. ot which the. following is a specification.

The object of the invention is to provide in a watering tank forrailroads an apparatus in which the conveying spout will be connectedwith a branch connection of the tank for universal movements whereby itcan be readily extended to any desired position.

A still further object of the invention is to provide means forfurnishing a perfect liquid tight joint at the point of swivelconnection of the spout with the discharge connection of the tank.

In the drawing forming a portionof this application and in which likeletters of reference indicate similar parts in the several views: Figure1 is a longitudinal section through the spout. Fig. 2 is a detailsectional view of the spout tov be described.

From any suitable form of tank (not illustrated) there extends a branchpipe 5, the latter being suitably secured to the side of the tank asshown. The branch pipe 5 is connected to the branch 28 by universaljoint or swivel 7 which includes an elbow 8 having a horizontal portion9 and a depending portion 10 and a similar elbow 11 which includes avertical portion 12 and a horizontal portion 13.

The horizontal portion 9 of the elbow 8 embraces the outer extremity ofthe branch pipe 5 of the tank, being disposed in spaced relation theretoand having its walls flared to present an angular seat 1/1 as shown. Anintegral collar 15 on the pipe 5 is embraced by the walls 9 of the elbow8 and as shown a spring 16 which is confined in the space 17 betweenthewalls 9 and the adjacent walls of the pipe 5 has one of its ends bearingagainst the collar 15 while its opposite end engages against a gasket orpacking 18 which is exteriorly tapered for frictional engagement withthe beveled seat 14: of the elbow whereby a liquid tight connection isformed at this point. From this construction it is evident that theelbow 8 is free to revolve upon the outer extremity of the pipe 5, thepurpose ot' which to be explained hereinafter. 'ith a view to preventingthe accidental disconnection of the elbow 8 from the pipe 5 I providewithin the walls 9 an annular stopvcollar 19, the same being cured tothe-wallsby one or more set screws or equivalent detachable tastenings20. yThe vertical depending portion l() of the elbow 8 is restricted ascompared with the previously described portion 9 ot' the elbow and asshown it extends into the large end 21 ot' the elbow '12. The said largeend has its walls spaced from the adjacent walls of the dependingportion 10 and mounted in the space aud surrounding said portion 10 is aspring 22, one end of which being engaged against a fixed collar 23ofthe portionl() while itsl opposite end bears against a gasket orpacking This packing embraces the portion 10 and is slidable thereon'and under the influence of the spring 22 it is yieldingly held againstthe annular seat ot' the elbow 12. A collar 26 which is substantiallyidentical with the collar 19 is secured within the walls of the portion21 of the elbow and is designed to engage against the collar 23 asshown.

The restricted portion 13 of the elbow 12 is interiorly threaded toengage with the threaded end 27 of an inner section 28 of a telescopicwater conducting spout. The outer section 29 of the spout has its innerportion provided with a yieldable gasket 30 which yieldingly engagesagainst the section 28 in order that the liquid tight connection will beformed at the joint between the section. The outer end of the section 29isl provided with an angularly extending neck 81 to be extended into thereservoir in the tender of the locomotive in the usual manner.

Incident to the peculiar details of construction of the device describedherein the spout may be extended angularly in either direction andlaterally or it may be adjusted to the full line positions as theoccasion may demand. In this manner the spout will be made to readilyaccommodate itself to the intake on the reservoir of the tender withoutdemanding definitely positioningthe locomotivewith relation to the tankwhich has been found desirable in that an engineer does not always bringhis enrafemea oct. 1o, 1916. ,Y
